Vercel is a cost source on /cost. An org that has connected a Vercel team adds it with one click and gets the team's daily billed charges per product, project and region, plan fees and credits included. An org with no Vercel team is sent to the existing connect flow. The source can be removed again, and the connection stays.
No new credential, no new table, no migration. The source is a cost_sources row that points at the existing vercel_connections row and reads with its token. Its account, and the account on its rows, is the team's id, which a slug rename leaves alone; the sources read answers the slug for the page to show. The row is the opt-in: adding creates it, removing deletes it.
Adapter (providers/vercel/): reads GET /v1/billing/charges (FOCUS JSONL) as a stream, line by line, and sums lines that share day, product, SKU, project, region and kind of charge. A line that is not a charge fails the whole pull as an invalid response, so part of a day is never stored. A charge's start must be a UTC date-time on a real calendar day, and its cost and quantity finite. Only a 200 is taken as the whole range: a 204 or a 206 fails the pull.
Sync profile: history starts at the first day of the month eleven months back, today included, so no window is longer than the year one request serves. The adapter refuses a window over 366 days. Today and yesterday are stored as not final. Requests are free, so none are counted.
Source service and API (GET / PUT / DELETE /internal/cost/vercel): the status read and the add sit behind the cloudCost flag, writes need integrations:manage and are audited as cost_sourcecreated / deleted, the actions the GitHub source uses. Adding names the team the dialog showed and reads yesterday and today once first, so a token whose role cannot read billing is refused in the dialog with the roles that can. A connection that reads another team by then, or whose token was replaced during that read, is refused as changed.
Lifecycle: the source goes when the org removes it, when Vercel is disconnected, and when the connection moves to another team (its spend would overwrite the source's days). A new token for the same team keeps the source and makes it due at the next tick. A reconnect decides between keeping and removing the source from the team it reads under the connection's lock.
Web: the Add source dialog lists Vercel and has a step for it (connected team, not connected, token rejected, already added, a refused add inline). The Sources row has Remove with a confirm and a link to the connection. Cost can be grouped and filtered by resource, which is the Vercel project: a Resource section in the filter rail, and a step in the row drill-down after regions (a service under a region goes on to its projects, a project to its services). Both show only where some cost names a resource, so an org without Vercel sees the page as it is on main. A Vercel team reads as "Vercel ", and one rule decides the logo of a service or region for every provider: a name that says whose it is (an AWS service name or region code, a GitHub product, a Vercel region id), then the org's only platform, else a neutral glyph. A resource is a GitHub repository or a Vercel project. The Group by control scrolls inside its own width, so the page does not pan sideways at narrow widths. The cost on show is emptied when a source is removed, for every provider, so no removed cost stays on screen while the reads run again or beside a failed one.
Docs: docs/cloud-cost-plan.md has the provider section.
Reconciled with the GitHub source on main
The dialog lists AWS, OpenRouter, GitHub and Vercel, and its note names every provider whose requests are free as one list.
GitHub's step with no organization connected puts Connect GitHub in the footer as the primary action, where Vercel's Connect button is.
Row actions say whose source they act on for every provider: Remove source, Replace key, Manage connection.
An unknown service in an org with several platforms gets a neutral glyph where main showed the AWS logo. One assertion of main's marks test said the AWS logo and now says neither logo.
The dialog says GitHub is read by product and repository again, now that the page has the Resource grouping.
Not verified live
The request and the response shape come from Vercel's OpenAPI spec. They have not been run against a real team: there was none to test with. Every field except BilledCost, ChargePeriodStart and ServiceName is read as optional for that reason. A request Vercel calls invalid (400) keeps Vercel's own message on the source and shows it in the dialog on an add, since the request is the part that is not proven. A 200 with an empty body reads as a team with no charges, and nothing in the answer tells that from a broken one: the doc lists it as an open risk.
How it was verified
Backend: 329 tests across the cost services (Vercel, GitHub, sync, plan), the cost reads, the Vercel integration and the audit tests. The adapter tests cover a body of several lines, blank lines and Windows line ends, an empty body and no body, a cut-off line, each refusal status, a rejected token, a window over a year and an unusable secret key. The service tests cover every refusal of an add.
Web: 67 tests in cost.scene.test.ts, marks.test.ts and cost-fixture.test.ts, main's GitHub cases included.
Typecheck of domain, backend, api and web. Lint with the CI config on every changed file. gen:anticipated-errors:check, ios:openapi:check, ui:patterns:check and ui:index:check pass.
Two independent reviews of the diff before the PR, and a third with the review bot after it. Their findings are fixed in the third, fourth and fifth commits.

Summary by CodeRabbit
New Features
Added Vercel as a cost source, with options to connect, add, view sync status, and remove it.
Vercel costs now sync with up to 12 months of history and display team and project details.
Added resource-based cost grouping, filtering, and drill-down.
Cost source lists now show account names when available, with clearer provider-specific actions.
Bug Fixes
Cleared stale cost data when sources are removed or no synchronized sources remain.
…nnection
An org's Vercel spend is read from the billing charges API: daily billed charges
per product, SKU, project and region, plan fees and credits included, as FOCUS
JSONL that is read line by line as it streams in.
The Vercel integration already holds the team and its token, so nothing new is
stored. The org adds its connected team on the Cost page, and that cost_sources
row is the opt-in: GET /internal/cost/vercel says whether a team is connected and
whether it is a source, PUT adds it after one read of yesterday (so a token whose
role cannot read billing is refused up front, with the roles that can), DELETE
removes it. The source also goes when the connection is deleted or moves to
another team, whose spend would overwrite the source's days. The sync only
removes sources whose connection is gone.
Vercel serves a year in one request, today included: the sync profile starts
history at the first day of the month eleven months back, and the adapter refuses
a window over 366 days. Today and yesterday are stored as not final. Requests are
free, so the source counts none.
The response shape is Vercel's OpenAPI spec and has not been run against a real
team. Everything but the three fields a row cannot do without is read as
optional, and a line that is not a charge fails the pull as an invalid response.
"Add source" lists Vercel. Its step reads the org's Vercel connection: a
connected team is added with one click, an org with none is sent to the connect
flow, and a team whose token Vercel rejected to its connection. An add Vercel
refuses stays in the dialog with the reason. A Vercel source has Remove on its
row, after a confirm that says the connection stays.
The remove dialog and its confirm now name the provider they act on, so the
OpenRouter and Vercel sources of one org are removed apart. The first-sync wait
names every provider that brings in months, and the cost lab has Vercel lines, a
Vercel source and a state for each step.
…new token, read the connection anew in the dialog
The dialog says Vercel is read per project, but the page could not show it: a
row's project is its resource, and the page had no such grouping. Cost can now be
grouped and filtered by resource.
A new token saved for the team a source reads makes that source due again at
once, and takes the claim of a pull still in flight on the old token. Before, the
source kept the old token's error and its hold of hours.
Adding the source reads yesterday and today, the days every daily pull ends on,
so the check asks what the sync will ask. A secret key Maple cannot use or a
connection deleted during the check no longer reads as a token Vercel refused. A
400 keeps Vercel's own message, a pull's timeout grows with its window, and an
add that changed nothing leaves no audit entry.
The Vercel step drops the answer on show each time it opens, so it never offers
an add on a connection read before it was left and a failed read says so. A
refused add links to the connection, where the token is replaced. In the cost
lab a state without a Vercel source no longer says it has one.
The change adds Vercel billing ingestion, source management, synchronization, and Cost page support. It also adds resource-based cost filtering and drill-down, updates lab scenarios, and documents the Vercel provider.

Summary
Cost contracts and API wiring packages/domain/src/cost.ts, packages/domain/src/http/vercel-cost.ts, packages/domain/src/http/internal-api.ts, packages/domain/src/http/index.ts, apps/api/src/routes/internal/vercel-cost.http.ts, apps/api/src/runtime/*-graph.ts
The domain adds the Vercel provider and status, add, and remove endpoints. The API registers handlers; add and remove check integrations:manage and write audit records only when they change a source.
Vercel billing stream and normalization packages/backend/src/services/integrations/vercel/api.ts, packages/backend/src/services/integrations/vercel/token.ts, packages/backend/src/services/cost/providers/vercel/*
The provider reads and decodes billing charges, maps errors, and aggregates charges into cost rows. The provider tests cover response parsing, error cases, and billing windows.
Source enrollment and connection lifecycle packages/backend/src/services/cost/VercelCostSourceService*, packages/backend/src/services/cost/vercel-cost-sources.ts, packages/backend/src/services/integrations/VercelIntegrationService*
The source service reports status, validates billing access before adding a source, and removes sources. Reconnects preserve source state for the same team and remove sources when the team changes or the connection is deleted.
Cost synchronization and history packages/backend/src/services/cost/sync-plan*, packages/backend/src/services/cost/CostSyncService*
Vercel uses an eleven-month history floor and a one-year request limit. The sync service registers the provider and reconciles Vercel sources with other cost sources.
The Cost page loads Vercel status, adds and removes the connected team, and displays its source and account name. Tests cover connection states, retries, stale reads, source actions, and removal.
Resource grouping and cost views apps/web/src/route/search.ts, apps/web/src/page/cost/{derive,view-filters,view-table,marks}.ts, apps/web/src/page/cost/{marks,cost.scene}.test.ts
Resource becomes a cost grouping and filter dimension. Facets, marks, labels, and drill-down account for available resource values.
Lab scenarios and plan apps/web/src/lab/cost-fixture*, apps/web/src/lab/cost-lab.ts, docs/cloud-cost-plan.md
The lab adds Vercel cost data, source lifecycle scenarios, and resource grouping. The plan describes the Vercel provider, API, lifecycle, and sync window.

Merge Risk: Low · up to f6218
Removing a Vercel source from a stale dialog could delete a newer team's source if the connection was changed from another tab, which stops that team's cost sync until it is re-added. The risk is narrow and recoverable, so it is worth fixing but should not block the rest of the feature.

…its slug, take only a whole answer
Adding a Vercel source names the team the dialog showed. A connection that reads
another team by then is refused as changed, where it used to become the source.
So is one whose token was replaced while the check read was in flight: the token
that passed the check was not the one the source would sync with.
A reconnect of the same team rewrites the connection's slug, which rows are
stamped with, while the source kept the slug from when it was added: one team
became two accounts. The source's account is now rewritten in that transaction.
A new token also makes the source due at the next tick. Clearing its hold was not
enough for one that had synced within the day.
Only a 200 is taken as the charges of the whole range: a 204 or a 206 fails the
pull, since storing them would leave days empty or by halves. A charge's
ChargePeriodStart must be a UTC date-time, not just start with a day.
A request Vercel calls invalid is shown in the dialog with Vercel's own message.
The upstream error it used to be is redacted, and the request shape has never run
against a real team. The adapter's failures carry what an add tells apart as a
field, in place of matching on their messages.
…sources, name row actions by provider
With seven options the Group by control was wider than the page at phone and
tablet widths and at a narrow desktop with the sidebar open, and the whole page
panned sideways. The control now scrolls inside its own width.
The window's reads are keyed by the window, not by the sources. When a removal
left no source with cost, the removed source's answers stayed in the model and
were shown again for the next source to sync over the same window. They are
dropped whenever no source has cost, for every provider.
The row actions say whose source they act on to assistive technology (Remove
Vercel source, Replace OpenRouter key, Manage AWS connection): two rows can
offer the same action. A Vercel row links to its connection, where the token is
replaced, and the dialog says so for a team that is a source already and has
lost its token.
In the cost lab a source added after its removal is a new one: it waits for its
first sync and has no cost, where it used to come back synced.
…ed Cost page
Main's Cost page now has a filter rail, a mark per key and a drill-down, and
"Usage type" is no longer a grouping. Its structure is kept as it is, with
Vercel and the Resource dimension added on top.
Resource stays as a sixth dimension: the page's design is one section and one
drill step per dimension, and a Vercel project is one more. The rail has a
Resource section and a row click reaches resources after regions (a service
under a region goes on to its projects, a project to its services). Both show
only where some cost names a resource, so an org without Vercel sees the page
main has. A filter by resource from the URL keeps its section.
A Vercel team reads as "Vercel <slug>" in the rail, the table, the legend and
the chips. Services and regions wear the logo of the platform that billed them
where that can be told: AWS by its service names and region codes, Vercel by its
region ids, and otherwise the org's only platform. With two platforms and a name
that says neither, the key gets a neutral glyph in place of the wrong logo.
The rail's values are dropped with the other reads when no source has cost. The
removable-provider type moved beside the messages, where the merge had made
model and message import each other.
…t have
The check of ChargePeriodStart took any day from 01 to 31 in any month, so
2026-02-31T00:00:00Z passed. Its cost would be filed under a day that does not
exist, which no window holds, and silently dropped. The day must now exist in
its month, a February 29th in leap years only, or the line fails the pull as an
invalid response.

…er the lock, refuse amounts that are not finite
A Vercel source's account, and the account on its rows, is now the team's id.
It was the slug, which a team can rename: rows already stored keep the account
they were pulled with, so a renamed team read as two accounts. The sources read
answers the team's slug as the account's name, for the page to show.
A reconnect chose between keeping and removing the cost source from a read of
the connection made before its transaction. A reconnect that committed in
between could leave the source of one team on a connection to another, or delete
the right one. The team is now read under the connection's lock, and the drain
reset and the cost source follow that.
A charge's cost and quantity must be finite: 1e309 is valid JSON and parses as
Infinity. Lines that are each finite and sum past what a number holds fail the
pull too.
The 403 guidance names every role Vercel lets read billing: Security and
Enterprise Viewer were missing. The sync test's Vercel stub has the read member
its service type requires; the backend typecheck leaves test files out, so that
was not caught.
…team connected now after a changed-connection refusal
A removal that left another synced source kept the old totals, series, breakdown
and rail on screen while they were read again, and a reread that failed left the
removed source's cost beside its error. The four are emptied when the removal
answers, for every provider, keeping their keys so a read from before it cannot
answer for the new one.
An add refused because the connection changed kept the old team in the dialog,
and the next click sent the same team again. The connection is read again after
that refusal, so the dialog shows the team to add now.
A Vercel team is labelled by the slug the sources read names it by, with its
team id as the key. The role guidance names all six roles.
On the note outside the diff (CostSyncService.test.ts, the Vercel stub without read): confirmed. The backend typecheck excludes test files, and the separate test typecheck is not part of CI, so nothing caught it. Fixed in 5171c5c: the stub is a full VercelCostProviderApi, and the one typing error of this PR's own in VercelCostProvider.test.ts is fixed with it.
Preview test and traces (head 4c04724830, app-pr-2542.maple.dev)
Run by a separate agent that had only this PR's description. The preview organization has no Vercel connection, so this covers the dialog, the Vercel step with nothing connected, the API's answers and the unchanged providers. Nothing here has run against a real Vercel team: the charge format still rests on Vercel's published reference.

…d Vercel on the Cost page
Main gained GitHub as a cost source and the read cache fix. Everything of
GitHub's is kept, with Vercel beside it and the page's rules made one for all
providers.
Marks: one rule decides whose a service or region is. A name that says so comes
first (an AWS service name or region code, a GitHub product, a Vercel region
id), then the org's only platform, else a neutral glyph. An unknown key in an
org with several platforms no longer wears the AWS logo as a guess.
Sources: a row's actions say whose source they act on for every provider
(Remove <Provider> source, Replace <Provider> key, Manage <Provider>
connection). Removal goes by the source, as main made it, and a Vercel source is
one more case of it. The cost on show is emptied when any removal answers.
Dialog: the list has AWS, OpenRouter, GitHub and Vercel, and its note names
every provider whose requests are free as one list. GitHub's step puts Connect
GitHub in the footer as the primary action beside Back, where Vercel's Connect
button is, so the two steps look the same.
Resource is a dimension for both: a GitHub repository and a Vercel project. The
dialog says GitHub is read by product and repository again, now that the page
has the grouping.
Vercel's audit entries use main's cost_source created and deleted actions; the
added and removed ones are gone. The sync runs one reconcile per provider, side
by side.
…urces of one provider
With two GitHub organizations as sources, both Remove buttons were named "Remove
GitHub source", and two AWS accounts shared "Manage AWS connection". When an org
has more than one source of a provider, the accessible name now carries the
account as its row shows it ("Remove GitHub source acme-labs", a Vercel team by
its slug). With one source the name stays as it was.

Adds Vercel as a cost source: a charges adapter, a cost-source service behind cloudCost with audited add and remove, the dialog step and a resource dimension on /cost. No new table or migration, and the tenant scoping and the connection-lock decisions hold. The VcsWebhookEnqueueFailure errors in http-graph.ts are untouched — this diff only registers the new route there, so it neither fixes nor worsens them.

Brings in the Vercel cost source (#2542). Main is the reference for what the
providers share, and Cloudflare is fitted into it:
- Marks: main's rule (a name first, then the org's only platform, else a glyph)
with Cloudflare's product names added to the known ones. My own mark rule and
its region helper are gone.
- Account label: a Cloudflare source now carries `accountName`, filled from the
account label stored with its token, so the page reads "Cloudflare <account
name>" where it showed the 32 character id.
- Row actions: main's naming, with the account when an org has two sources of a
provider. A pasted credential's Replace and Remove go through it.
- Dialog: main's rows, footnote, GitHub and Vercel steps as they are. The pasted
credential step stays one form described by data, used for both providers.
- Removal, the first-sync table, the empty state and the lab follow main, with
Cloudflare added beside the others.

What changed
Vercel is a cost source on
/cost. An org that has connected a Vercel team adds it with one click and gets the team's daily billed charges per product, project and region, plan fees and credits included. An org with no Vercel team is sent to the existing connect flow. The source can be removed again, and the connection stays.No new credential, no new table, no migration. The source is a
cost_sourcesrow that points at the existingvercel_connectionsrow and reads with its token. Its account, and the account on its rows, is the team's id, which a slug rename leaves alone; the sources read answers the slug for the page to show. The row is the opt-in: adding creates it, removing deletes it.providers/vercel/): readsGET /v1/billing/charges(FOCUS JSONL) as a stream, line by line, and sums lines that share day, product, SKU, project, region and kind of charge. A line that is not a charge fails the whole pull as an invalid response, so part of a day is never stored. A charge's start must be a UTC date-time on a real calendar day, and its cost and quantity finite. Only a 200 is taken as the whole range: a 204 or a 206 fails the pull.GET/PUT/DELETE /internal/cost/vercel): the status read and the add sit behind thecloudCostflag, writes needintegrations:manageand are audited ascost_sourcecreated/deleted, the actions the GitHub source uses. Adding names the team the dialog showed and reads yesterday and today once first, so a token whose role cannot read billing is refused in the dialog with the roles that can. A connection that reads another team by then, or whose token was replaced during that read, is refused as changed.docs/cloud-cost-plan.mdhas the provider section.Reconciled with the GitHub source on main
Not verified live
The request and the response shape come from Vercel's OpenAPI spec. They have not been run against a real team: there was none to test with. Every field except
BilledCost,ChargePeriodStartandServiceNameis read as optional for that reason. A request Vercel calls invalid (400) keeps Vercel's own message on the source and shows it in the dialog on an add, since the request is the part that is not proven. A 200 with an empty body reads as a team with no charges, and nothing in the answer tells that from a broken one: the doc lists it as an open risk.How it was verified
